Hence in the wise leader's plans,considerations of advantage and of disadvantage will be blended together.If our expectation of advantage be tempered in this way,we may succeed in accomplishing the essential part of our schemes.If,on the other hand,in the midst of difficulties we are always ready to seize an advantage,we may extricate ourselves from misfortune.
智慧明达的将帅考虑问题,必然把利与害一起权衡.在考虑不利条件时,同时考虑有利条件,大事就能顺利进行；在看到有利因素时同时考虑到不利因素,祸患就可以排除.
